Description

Technical Field

[0001] The present invention relates to the technical field of satellite communications, and in particular to an antenna bracket. Background Art

[0002] With the rapid increase in demand for government and civil emergency communications, the demand for satellite communication products is also increasing. Satellite communication has become one of the main transmission methods of communication today. It mostly uses satellite antennas to transmit and exchange data information. At this time, it is necessary to align the antenna. The aligning bracket is the main structure for realizing the aligning operation. The adjustment mechanism of the aligning bracket determines the aligning efficiency, stability after the aligning is completed, and the overall wind resistance of the equipment. The aligning bracket in the prior art generally includes a base, a shelf and a pitch adjustment bracket. The shelf is used to carry target items. The length of the pitch adjustment bracket can be adjusted telescopically. The lower end of the shelf is directly hinged to one end of the base, and the two ends of the pitch adjustment bracket are respectively hinged to the upper end of the shelf and the other end of the base. The pitch angle of the shelf can be adjusted by adjusting the length of the pitch adjustment bracket, that is, the inclination of the shelf's storage plane can be adjusted. However, since the relative position between the lower end of the rack and the base remains unchanged, as the pitch angle of the rack increases, the center of gravity of the satellite bracket and the equipment on the rack will move forward, reducing the stability of the satellite bracket and making it less wind-resistant.

[0003] Therefore, how to solve the problem of the center of gravity of the satellite alignment bracket and the equipment moving forward when the pitch angle is adjusted in the prior art becomes an important technical problem to be solved by those skilled in the art. Summary of the invention

[0013] Preferably, the telescopic assembly is slidably connected to the base, and the sliding direction is perpendicular to the rotation axis of relative rotation between the storage rack and the base.

[0014] Preferably, the telescopic assembly comprises a first support plate and a second support plate arranged parallel to each other, and a slide rail structure is arranged between the first support plate and the second support plate so that the first support plate can move relative to the second support plate along the length direction of the second support plate.

The fourth rod is rotatably connected to the base, and the fourth rod is provided with a strip groove extending along the length direction of the fourth rod. One end of the stud is fixedly connected to the third rod, and the other end passes through the strip groove and is screwed and connected with the locking nut.

[0018] Preferably, two groups of the connecting rod mechanisms are provided, and the two groups of the connecting rod mechanisms are respectively located on both sides of the storage rack.

[0019] The technical solution provided by this application includes the following beneficial effects:

[0020] The present application provides an antenna bracket, comprising a base, a shelf for carrying target items, a connecting rod mechanism and a locking mechanism, wherein the base is arranged horizontally, the shelf can be rotated relative to the base, the axis of relative rotation is arranged in the horizontal direction, and the inclination angle of the shelf can be adjusted by rotating the shelf relative to the base. The connecting rod mechanism is arranged between the shelf and the base, and the connecting rod mechanism comprises a first rod, a second rod, a third rod and a slider, the slider is slidably connected to the base, and the sliding direction is perpendicular to the axis of relative rotation between the shelf and the base, the two ends of the first rod are rotatably connected to the slider and the shelf respectively, the two ends of the third rod are rotatably connected to the base and the shelf respectively, the second rod is located between the first rod and the third rod, and the two ends of the second rod are rotatably connected to the slider and the middle of the third rod respectively. The connection position between the third rod and the base is located at the first end of the base, and the connection position between the first rod and the shelf is located at the second end of the shelf. The locking mechanism is used to lock the state of the connecting rod mechanism. The third rod, the second rod, the slider and the base constitute a crank slider mechanism. The third rod is equivalent to the crank, and the second rod is equivalent to the connecting rod. After the movement of any one of the crank, the connecting rod or the slider is restricted, the state of the crank slider mechanism will be locked, and accordingly, the state of the connecting rod mechanism is also locked. When the locking mechanism is in the first state, the slider can move back and forth on the base, and the angle between the third rod and the second rod and the angle between the first rod and the rack will change accordingly. Correspondingly, the inclination angle of the rack will change, and the inclination angle of the rack can be adjusted at this time; when the locking mechanism is in the second state, the locking mechanism limits the relative movement of the slider on the base, so that the operation of the crank slider mechanism is restricted, the relative position of the third rod and the second rod and the relative position between the first rod and the rack are fixed, and accordingly, the inclination angle of the rack is locked. In this way, when the inclination angle of the rack increases, the angle between the third rod and the rack increases. Since the two ends of the second rod are respectively connected to the third rod and the slider, and the slider can only slide on the base, the angle between the third rod and the second rod increases, and at the same time drives the slider to move toward the first end of the base. The movement of the slider drives the first rod and the second end of the rack to move toward the first end of the base, so that the center of gravity of the rack and the equipment thereon as a whole moves toward the first end of the base, so that the center of gravity of the antenna bracket and the equipment as a whole gradually approaches the center of gravity of the antenna bracket, thereby avoiding the forward movement of the center of gravity of the antenna bracket and the equipment, and improving the stability and wind resistance of the antenna bracket. At the same time, the two ends of the first rod are respectively connected to the slider and the second end of the rack. The movement of the slider increases the angle between the first rod and the rack, and the angle between the first rod and the base, thereby increasing the distance between the second end of the rack and the base, and increasing the gap between the equipment on the rack and the base. The gap can avoid interference with the base when the equipment rotates polarization.

[0037] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0038] The purpose of this specific implementation is to provide an antenna bracket to solve the problem of the center of gravity of the satellite alignment bracket and the device moving forward when the pitch angle is adjusted in the prior art.

[0039] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention described in the claims. In addition, the entire contents of the configurations shown in the following embodiments are not limited to the solutions required as the invention described in the claims.

[0040] Reference Figures 1 to 12, showing a schematic diagram of the structure of the antenna bracket in some exemplary embodiments. An antenna bracket provided in this embodiment includes a base 1, a shelf 2 for carrying target items, a connecting rod mechanism and a locking mechanism, wherein the base 1 is arranged horizontally, the shelf 2 can rotate relative to the base 1, and the axis of relative rotation is arranged in the horizontal direction. By rotating the shelf 2 relative to the base 1, the inclination angle of the shelf 2 can be adjusted. The above-mentioned connecting rod mechanism is arranged between the shelf 2 and the base 1, and the connecting rod mechanism includes a first rod 3, a second rod 4, a third rod 5 and a slider 6. The slider 6 is slidably connected to the base 1, and the sliding direction is perpendicular to the rotation axis of relative rotation between the shelf 2 and the base 1. The two ends of the first rod 3 are rotatably connected to the slider 6 and the shelf 2 respectively, and the two ends of the third rod 5 are rotatably connected to the base 1 and the shelf 2 respectively. The second rod 4 is located between the first rod 3 and the third rod 5, and the two ends of the second rod 4 are rotatably connected to the middle of the slider 6 and the third rod 5 respectively. The connection position between the third rod 5 and the base 1 is located at the first end of the base 1 , and the connection position between the first rod 3 and the rack 2 is located at the second end of the rack 2 .

[0041] The third rod 5, the second rod 4, the slider 6 and the base 1 constitute a crank slider mechanism, the third rod 5 is equivalent to the crank, the second rod 4 is equivalent to the connecting rod, and the base 1 is equivalent to the frame. The movement of any one of the crank, the connecting rod or the slider is restricted, and the state of the crank slider mechanism will be locked. Correspondingly, the state of the connecting rod mechanism is also locked. The locking mechanism is used to lock the state of the connecting rod mechanism. The specific structure of the locking mechanism is not specifically limited here. Any structure that can achieve the locking of the state of the connecting rod mechanism belongs to the protection scope of the present invention. When the locking mechanism is in the first state, the slider 6 can reciprocate on the base 1, and the angle between the third rod 5 and the second rod 4 and the angle between the first rod 3 and the rack 2 will change accordingly. Correspondingly, the inclination angle of the rack 2 will change, and the inclination angle of the rack 2 can be adjusted at this time; when the locking mechanism is in the second state, the locking mechanism limits the relative movement of the slider 6 on the base 1, so that the operation of the above-mentioned crank slider mechanism is restricted, the relative position of the third rod 5 and the second rod 4 and the relative position of the first rod 3 and the rack 2 are fixed, and accordingly, the inclination angle of the rack 2 is locked.

[0042] With such arrangement, when the inclination angle of the storage rack 2 increases, the angle a between the third rod and the storage rack increases. Since the two ends of the second rod 4 are respectively connected to the third rod 5 and the slider 6, and the slider 6 can only slide on the base 1, the angle b between the third rod and the second rod increases, and at the same time drives the slider 6 to move toward the first end of the base 1. The movement of the slider 6 drives the first rod 3 and the second end of the storage rack 2 to move toward the first end of the base 1, so that the center of gravity of the storage rack 2 and the equipment thereon as a whole moves toward the first end of the base 1, so that the center of gravity of the antenna bracket and the equipment as a whole gradually approaches the center of gravity of the antenna bracket, thereby avoiding the forward movement of the center of gravity of the antenna bracket and the equipment, and improving the stability and wind resistance of the antenna bracket. At the same time, the two ends of the first rod 3 are respectively connected to the slider 6 and the second end of the rack 2. The movement of the slider 6 increases the angle c between the first rod and the rack, and the angle d between the first rod and the base, thereby increasing the distance h between the second end of the rack and the base, and increasing the gap between the device on the rack 2 and the base 1. The gap can avoid interference with the base 1 when the device rotates and polarizes.

[0043] It should be noted that the front of the antenna bracket refers to the side of the shelf 2 where the device can be installed, that is, the side of the shelf 2 away from the base 1 and the connecting rod mechanism.

[0044] In practice, the locking mechanism may be disposed between the base 1 and the rack 2, or between the base 1 and the slider 6. At this time, the locking mechanism includes a telescopic component with adjustable length and a locking component for locking the length of the telescopic component.

[0045] like Figures 6-7 As shown, the telescopic assembly can be arranged between the base 1 and the slider 6, one end of the telescopic assembly is fixedly connected to the base 1, and the other end is fixedly connected to the slider 6. At this time, the state of the connecting rod mechanism can be locked directly by limiting the movement of the slider 6. It should be noted that the connection between the telescopic assembly and the base 1 and the slider 6 can also be a rotational connection.

[0046] As an optional embodiment, the telescopic assembly can also be arranged between the base 1 and the rack 2, referring to Figures 1 to 4, one end of the telescopic assembly is rotatably connected to the base 1, and the other end is rotatably connected to the first end of the rack 2. At this time, when the overall length of the telescopic assembly is locked, since the slider 6 can only move in the horizontal direction along the direction perpendicular to the rotation axis of the relative rotation between the rack 2 and the base 1, and the movement of the rack 2 in any direction will cause the slider 6 to move, the movement of the slider 6 will inevitably change the angle b between the third rod and the second rod and the angle c between the first rod and the rack, and the shape of the quadrilateral formed by the first rod 3, the second rod 4, the third rod 5 and the rack 2 and the angle a between the third rod and the rack will inevitably change, and the rack 2 cannot move vertically downward under gravity, and the rack 2 will definitely produce a rotational movement around the rotation axis between the first end of the rack 2 and the telescopic assembly, that is, the angle e between the telescopic assembly and the rack will change. The quadrilateral formed by the telescopic assembly, the base 1, the third rod 5 and the rack 2 is called the first quadrilateral, and the quadrilateral formed by the first rod 3, the second rod 4, the third rod 5 and the rack 2 is called the second quadrilateral. Since the ratios of the lengths of the sides of the first quadrilateral and the second quadrilateral are different, the changes in the angles in the first quadrilateral and the second quadrilateral must be different. Only when the overall length of the telescopic assembly can be changed, the changes in the angles in the first quadrilateral and the second quadrilateral will be the same. Therefore, when the overall length of the telescopic assembly is locked, the state of the connecting rod mechanism is immediately locked, and the tilt angle of the rack 2 is locked.

[0047] In practice, the telescopic assembly includes a first support plate 7 and a second support plate 8, which are arranged parallel to each other. A slide rail structure is arranged between the first support plate 7 and the second support plate 8, so that the first support plate 7 can move relative to the second support plate 8 along the length direction of the second support plate 8. By moving the first support plate 7 and the second support plate 8 relative to each other, the overall length of the telescopic assembly can be adjusted.

[0048] In practice, the above-mentioned slide rail structure includes a first slide groove arranged on the first support plate 7, the extension direction of the first slide groove is consistent with the length direction of the first support plate 7, and the first end of the second support plate 8 can extend into the first slide groove and reciprocate along the length direction of the first slide groove. A limiting structure for limiting the second support plate 8 from escaping from the first slide groove is arranged between the first support plate 7 and the second support plate 8, which can be a first limiting block arranged at the second end of the first support plate 7 and a second limiting block arranged at the first end of the second support plate 8, and the first limiting block is located on the side wall of the first slide groove. When the first end of the first support plate 7 and the second end of the second support plate 8 are away from each other to the maximum distance, the first limiting block at the second end of the first support plate 7 interacts with the second limiting block at the first end of the second support plate 8, and the first limiting block limits the movement of the second limiting block, thereby preventing the second support plate 8 from escaping from the first slide groove.

[0049] Specifically, the first support plate 7 includes a first plate member and a second plate member that are overlapped, and the first slide groove is in an open state and is arranged on a side of the first plate member close to the second plate member. A plurality of threaded holes are arranged on the first plate member and the second plate member, and the plurality of threaded holes are distributed on both sides of the first slide groove, and the first plate member and the second plate member are fixed by bolts.

[0050] During use, it is inevitable that dust or particles will enter between the second support plate 8 and the first chute, which will affect the relative sliding smoothness between the first support plate 7 and the second support plate 8. In the preferred solution of this embodiment, a sand discharge groove 14 is provided on the side wall of the first chute and the outer surface of the second support plate 8, and the dust or particles entering between the second support plate 8 and the first chute will be discharged through the sand discharge groove 14.

[0051] In this embodiment, the locking assembly includes a locking screw 9 and a threaded through hole for the locking screw 9 to be screwed into. The threaded through hole is arranged on the side wall of the first slide groove on the first support plate 7. After the threaded end of the locking screw 9 is screwed into the threaded through hole on the first support plate 7, the end is pressed against the surface of the second support plate 8, thereby achieving the fixation of the relative position between the first support plate 7 and the second support plate 8, that is, the overall length of the telescopic assembly is locked.

[0052] It should be noted that the rotation axis of the above-mentioned rotation connection is parallel to the rotation axis of the relative rotation between the storage rack 2 and the base 1.

[0053] Furthermore, the telescopic assembly also includes a fine adjustment assembly 10 disposed between the second end of the second support plate 8 and the base 1. After the overall length of the telescopic assembly is roughly adjusted by adjusting the relative position between the first support plate 7 and the second support plate 8, the fine adjustment assembly 10 can be used to further adjust the overall length of the telescopic assembly, thereby improving the adjustment accuracy of the overall length of the telescopic assembly. The above-mentioned fine adjustment assembly 10 includes a first screw rod, a second screw rod and a connecting member arranged coaxially. The first end of the first screw rod is fixedly connected to the second end of the second support plate 8, and the second end of the second screw rod is connected to the base 1. If the telescopic assembly is arranged between the base 1 and the slider 6, the second end of the second screw rod can be fixedly connected to the base 1. If the telescopic assembly is arranged between the base 1 and the storage rack 2, the second end of the second screw rod is rotatably connected to the base 1. The thread rotation direction of the first screw rod is opposite to that of the second screw rod. The connecting member is a columnar structure extending along the axial direction of the first screw rod and the second screw rod. A first threaded hole threadedly matched with the second end of the first screw rod and a second threaded hole threadedly matched with the first end of the second screw rod are respectively arranged at both ends of the connecting member. The first threaded hole and the second threaded hole can be connected. When the connecting member is rotated, the movement direction of the connecting member relative to the first screw is opposite to the relative movement direction of the connecting member relative to the second screw, that is, when the connecting member is rotated, the second end of the first screw and the first end of the second screw will approach each other or move away from each other, so that the overall length of the telescopic assembly changes.

[0054] Furthermore, the telescopic assembly can be slidably connected to the base 1, and the sliding direction is perpendicular to the relative rotation axis between the rack 2 and the base 1. Figure 5 At this time, by adjusting the relative position between the end of the telescopic assembly and the base 1, the tilt angle of the rack 2 can be adjusted. Correspondingly, by locking the relative position between the end of the telescopic assembly and the base 1, the tilt angle of the rack 2 is also locked. Specifically, a third slide groove 17 can be provided on the base 1, and the length direction of the third slide groove 17 is perpendicular to the relative rotation axis between the rack 2 and the base 1. A connecting shaft is provided at the end of the telescopic assembly or the end of the fine adjustment assembly 10. After the end of the connecting shaft passes through the third slide groove 17, it can be screwed and connected with a nut.

[0055] During implementation, a second slide groove 11 is provided on the base 1 and coincides with the sliding track of the slider 6. The slider 6 is embedded in the second slide groove 11 and can move along the extension direction of the second slide groove 11. The second slide groove 11 can limit the moving direction of the slider 6 and guide the movement of the slider 6.

[0056] In practice, a second groove 13 for accommodating the connecting rod mechanism is provided on the base 1, and the second slide groove 11 is provided on the side wall of the second groove 13. When the inclination angle of the rack 2 is zero, the lower surface of the rack 2 contacts the upper surface of the base 1, and the position of the connecting rod mechanism is the position of the second groove 13, and the size of the second groove 13 needs to be slightly larger than the space occupied by the connecting rod mechanism.

[0057] When the telescopic assembly is arranged between the rack 2 and the base 1, a first groove 12 for accommodating the locking mechanism is arranged on the base 1. When the inclination angle of the rack 2 is zero degrees, the lower surface of the rack 2 contacts the upper surface of the base 1, and the position of the locking mechanism is the position of the first groove 12. The size of the first groove 12 needs to be slightly larger than the space occupied by the locking mechanism.

[0058] When the telescopic assembly is disposed between the base 1 and the slider 6 , the telescopic assembly can be located below the base 1 .

[0059] The locking mechanism can also be arranged between any two of the base 1, the first rod 3, the second rod 4 and the third rod 5. Figures 8 to 11 shown.

[0060] The structure of the locking mechanism is described below by taking the example of the locking mechanism being arranged between the base 1 and the third rod 5. Fig.10 The locking mechanism includes a fourth rod 15, a stud and a locking nut. The fourth rod 15 is rotatably connected to the base 1. The fourth rod 15 is provided with a strip groove 16 extending along the length direction of the fourth rod 15. One end of the stud is fixedly connected to the third rod 5, and the other end passes through the strip groove 16 and is screwed and connected with the locking nut. By adjusting the position of the stud in the strip groove 16, that is, adjusting the relative position between the fourth rod 15 and the third rod 5, the tilt angle of the rack 2 can be adjusted. Accordingly, by locking the relative position between the fourth rod 15 and the third rod 5 through the locking nut and the stud, the tilt angle of the rack 2 is also locked.

[0061] It should be noted that the strip groove 16 can also be provided on a rod member in the connecting rod mechanism that is slidably connected to the fourth rod member 15, such as Fig.11 As shown, when the locking mechanism is arranged between the second rod 4 and the third rod 5, one end of the fourth rod 15 is rotatably connected to the third rod 5, the strip groove 16 is arranged on the second rod 4, one end of the stud is fixedly connected to the fourth rod 15, and the other end is screwed and connected with the locking nut after passing through the strip groove 16. By adjusting the position of the stud in the strip groove 16, that is, adjusting the relative position between the fourth rod 15 and the second rod 4, the tilt angle of the rack 2 can be adjusted. Accordingly, by locking the relative position between the fourth rod 15 and the second rod 4 through the locking nut and the stud, the tilt angle of the rack 2 is also locked.

[0062] When the above-mentioned connecting rod mechanism is provided in one group, the strength of the connecting rod mechanism can be increased by increasing the width or thickness of the first rod 3, the second rod 4 and the third rod 5. In practice, the above-mentioned connecting rod mechanism is provided in two groups, and the two groups of connecting rod mechanisms are respectively located on both sides of the storage rack 2, thereby increasing the strength and stability of the antenna bracket. When the above-mentioned telescopic assembly is provided between the base 1 and the slider 6, a connecting rod is provided between the sliders 6 of the two groups of connecting rod mechanisms, so that the first support plate 7 of the telescopic assembly is fixedly connected to the connecting rod. In addition, the strength of the connecting rod mechanism can also be increased by additionally increasing the number of rods and sliders on one side of the connecting rod mechanism, such as Fig.12 shown.

[0063] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
